Is there anyone who could tell the truth...89year RC600 cylinder bore is 98mm or 99mm?
It does not so much matter, except spareparts I have are for 98mm bore.

I found behind the corner one really nice unit. Only 6811km on the clock and thats all. Like a new, only some minor sign of usage. Owner was old man who told me that every year he has made a short run it. Even the front tyre is original!

Revlimiter is a bit strange, it should go 2nd gear 78km/h, but it goes only 69km/h. 3rd gear 98km/h and should go 107km/h. Rest gears are not tested. Don,t know how much it rev as this model is without tacho, only temp and clock.

Also it is thirsty bike, around 6-7l/100km with cruising speeds (70-110Km/h). And it is still making some jerking, like a lean mixture. (I cleaned the carb, no big changes). Maybe todays fuel with alcohol is not so good for oldies???

This kit should be originally made by mr. Frigerio, not sure but....only thing I know is that rear tank is missing.

If anyone have more information, please let me know. How many tank ever made and so on.

Yesterday I got those back from painting job. Still some fasteners must be done and fuel pump installation. I tried the pump witch comes within the kit, too high pressure, need some pressure relief valve.

Next thing is the new exhaust, I like to do pipes like this:

All the trucks made before 1993 are here in Africa and still moving slowly with lots of smoke and no brakes!!
A loud exhaust is a safety feature even the goats and chickens scatter out of the way, camels (not Morini's) don't and they are too big to argue with.
I'm looking forward to seeing photo's when it's finished.
I bought an RC when in the uk in September, it has spent many years unused in a farm building and looks very scruffy but when cleaned up will go well with my Nordwest I think.

Hi Jori, if you need more fuel-capacitie; so I had builded in past a front-(down)-spoiler, included 5 Ltr. Tested by Sam (Switzerland) If you need some: I can build it ( but needs some times, so my heatlth is not the best at the moment).

1. How bad quality fuel can be used on gilera engine without any modification? Just asking cause may be that next two trips goes East and more far away East. There is normal to get 80-92octane or lowest I have heard is 72octane (new bmw gs was fine with it). Here where I live standard octane rate is 95, 98 and 99oct. Do you see that I can expect some problems? Should I fix adjustable ignition box (ignitech)?

2. What will be the weakest point on rc600 if we are thinking about 20tkm trip? (ok, I know that it may be necessary to change belt and oil, something else)

3.can anyone give any good numbers and source for front forks springs, with big tanks standard are too soft.

Wilbers have progressive springs for RC, I may try those with littlebit more stiffer than originals.

4. rear shock must be better too, bitubo or?
I am thinking to go Wilbers, not standard ,but builded with specs I will give.
